How do I make groups in 2.8?
Groups and Layers in 2.80 were scrapped and merged into the same thing now for 2.8.
These things are called Collections.
Open an Outliner Editor. Click the &quot;Display Mode&quot; button in the header and select &quot;View Layer&quot; from the dropdown menu.
You can make a new collection by right-clicking and pressing &quot;New&quot;.

Then you can rename your new Collection.

Then in the Properties Editor, you assign your collection to be simulated in a particle system.
